The titlepage shows a female announcer at a fair, wearing a Phrygian cap, drawing aside a curtain to reveal the contents of the menagerie which is 'composée de ruminants, amphibies, carnivores et autres budgetivores qui ont dévoré la France pendant 20 ans'. The 31 following prints place a head of a prominent figure of the Third Empire, beginning with Napoeon III and Eugenie, onto bodies of birds and other animals. Each caricature is identified along the top.
